Why? Because... well, I have them both, and they're both CMOS 1080/24 and 720/60 cameras, and ... they both cost the same, so... why not?
So, what can we learn from this? In 720p mode, the Canon is slightly less skewy than the HMC40; the HMC40's pipe has a little bit more lean to it than the 7D does.
In 1080, the situation is reversed, and moreso -- the Canon is noticeably more skewed than the Panasonic.
But, the conclusion you cannot draw from this is how either of them, in 720 mode, compare to their own selves in 1080 mode. This test was not a scientific speed-timed test that could be used to compare from one test run to the other. This test was conducted in such a way that the only comparison that can be drawn is between the two cameras, at the exact same frame.
Test details: white-ish PVC pipe set up against a black surface. Two cameras mounted on a flat platform on the same tripod head, side by side, zoomed in to identical field of view (so relative magnification should be absolutely identical). Frames sync'd by the old hand-clap technique. Then the tripod head was jerked side to side past the pipe; that pipe is actually standing up straight, but the skew of both cameras renders it as leaning. And yes, this was a very high-speed pan. Both cameras set to 1/500 shutter to freeze the pipe, and therefore the pipe was lit up by two 6-bank fluorescents and a 150w HMI.
Then, in post, I sync'd them so that the files were representing the exact same frames on the timeline, found a couple of frames, and pulled 'em into photoshop. I cropped out the black parts off the Canon frames and copied the pipe on top of the Panasonic frame, and -- well, there it is.
